Specification of Letters Patent.

Patented July 16, 1907.

Application filed April 15, 1907. Serial No- 368,283-

To all whom it may concern:

Be it -known that we, EDWARD M. OoeHLAN and GEORGE W. FIFE, citizens ofthe United States, residing at Indianapolis, in the county of Marion andState of Indiana, have invented certain new and useful Improvements inTrick Lung-Testers; and we do declare the following to be a full, clear,and exact description of the invention, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

This invention relates to a machine that is designed for the amusementof persons who may ascertain approximately what capacity they may havefor blowing forcibly, and is intended to be used more particularly bygroups of persons in amusing contests in a display of strength and skillin blowing to operate an indicator which is supposed to indicate therelative strength of their lungs, the machine having reference also toapparatus whereby a trick may be played to the discomfiture of one ofthe contestants who may blow into the machine, whereby a jet of watermay be blown or forced from the machine into his face.

The object of the invention is to provide a machine of theabove-mentioned character which will afford healthful amusement andentertainment, and whereby innocent and harmless tricks may be performedfor the amusement of the company.

With the above-mentioned and minor objects in view, the inventionconsists in a trick-lung tester comprising an inclosing case providedwith a dial and indieating pointer, a wind-wheel and connectingmechanism whereby the pointer may be actuated, means for retracting thepointer to the zero mark or its normal position, a conduit connectedwith the wind wheel and extending out through the case so as to beaccessible to the operator, a vessel in the case for containing water orsimilar liquid, a conduit leading from the vessel through the front ofthe case, a tube for filling the vessel, and means whereby communicationmay be opened either between the conduit into which the operator blowsand the wind-wheel, or between the conduit into which the operator blowsand the vessel. And the invention consists further in the novel partsand in the combinations and arrangements of parts as hereinafterparticularly described and defined in the appended claims.

Referring to the drawings Figure 1 is a perspective view of the improvedtrick lung tester; Fig. 2, a vertical sectional view taken at a planethrough the case near the back or rear part thereof; Fig. 3, a verticaltransverse sectional view approximately on the line A A in Fig. 2; Fig.4, a vertical central transverse sectional view; Fig. 5, a fragmentaryrear elevation broken away and shown in vertical section approximatelyon the line B B in Fig. 3; Fig. 6, a horizontal sectional view on theline C C in Fig. 3; Fig. 7, a top plan of the pointer-operatingmechanism separate from the case; Fig. 8, a horizontal sectional view onthe line D D in Fig. 2; Fig. 9, a fragmentary vertical sectional view onthe line E in Fig. 3, showing parts of the mechanism in which a portionof the conduit leading to the wind wheel is shown in section on adifferent plane; Fig. 10, a fragmentary horizontal sectional viewapproximately on the line F F in Fig. 2; Fig. 11, a horizontal sectionalview showing a modified construction for changing the air current to orfrom the windwheel or the vessel taken at a plane above the vessel; Fig.12, a fragmentary sectional view showing the stopper for the fillingtube of the vessel; Fig. 13, a fragmentary vertical sectional view onthe line G G in Fig. 10; Fig. 14, a front view of the valve comprisingpart of the modifications shown in Fig. 11; Fig. 15, a fragmentaryhorizontal sectional view on the line H H in Fig. 14; Fig. 16, asectional view similar to Fig. -15 but with the position of the valveplug changed; and Fig. 17, a fragmentary vertical sectional view on theline I I in Fig. 15.

Similar reference characters in the several figures of the drawingsdesignate corresponding elements or features of construction.

The present invention comprises in construction an inclosing case whichmay be variously constructed, being preferably composed of a bottom a, afront b and suitable sides together with a top 0, and a hinged door (Iforming the back of the case. A suitable frame e is secured to the upperportion of the front I) in the interior of the case, and a spindle f ismounted rotatively in the frame so as to extend through the forward partof the frame, the spindle having a gear wheel 9 and also a pinoin hsecured thereto near the inner end thereof. A dial i is mounted in thefront of the case and a pointer j is secured to the outer end of thespindle f at the front of the dial. A rock-shaft k is journalcd also inthe frame e and has a gear wheel l secured thereto in engagement withthe pinion h, a spring m being mounted on the rock-shaft and having oneend secured thereto, and an end connected to a rod e of the frame 6 forthe purpose of retracting the pointer j to the zero mark on the dialafter having been operated. The frame e is provided with a stop finger nthat projects near the wheel Z, and the latter is provided with a pin oto engage the finger for stopping the pointer at the zero mark when saidwheel is rotated, by means of the tension of the spring m, the pin 0being moved away from the finger during operation of the pointer. Adrive-shaft p is mounted rotatively also in the frame e and has a pinionq and also a suitable wind wheel 1 secured thereto, the pinion being inengagement with the wheel g for operating the pointer j. A blast pipenozzles is mounted on the frame e so as to direct the air currents tothe blades of the wind-wheel in order to rotate the wheel, and thusutilize the force of the air current produced by the blowing of theoperator.

A pipe connection 1; is mounted at the inner side of the lower portionof the front b, and a blow pipe t which is preferably flexible, as arubber tube, is connected thereto, the connection having two branches uand u. A housing 1) is suitably supported in the case and has a pivotbar 1) and also a guide-opening, at two opposite sides of which arerounded abutments w and w, two air tubes :0 and x extending through theopening close to the abutments and connected to the branches'u and u.The air tube as is connected to a vessel y which is suitably supportedin the case and is normally closed except for the connecting tubes orconduits. The air tube at is attached to the blast pipe connection 5 anda tube-closer z of bar shape is connected at one end thereof by a pivot18 to the pivot barn and extends through the opening in the housingbetween the air tubes as and x, and is provided with an operating arm 2which extends through the case at any suitable point but preferably ashereinafter described. The tubes a; and x are rubber so that they maycollapse, and the purpose of the tube-closer z is' to press either tubeagainst the abutment adjacent thereto so as to flatten the tube and thusprevent air from passing through it, all operating substantially as avalve for changing the direction of the air currents either to the windwheel or to the vessel.

In the upper portion of the front his aminute nozzle 19 so arranged asto not readily be observed by the operator, and a tube 20 connects thenozzle with the vessel y, the tube having an extension 21 from the topnearly to the bottom of the vessel so that a jet'of water may be ejectedfrom the vessel out of the nozzle 19 into the face of the operator. Afilling tube 22 is connected to the vessel and has a funnel shaped top23 mounted in the top 0 of the case, the funnel serving as a V valveseat to which a valve shaped stopper 24 is connected removably so thatthe vessel may be readily filled when the stopper is removed, the latterhaving a disguising ornamental shape so as to not be noticeable as afilling plug. The top of the case is preferably provided with a carryinghandle or bail 25.

As preferably constructed the door d has a horizontal slot 26 thereinthrough which the arm 2 extends, there being notches 27 and 28 at thesides of the slot into which the arm may be latched to retain it in thedesired position.

In some cases the modifications above referred to may be employed whichcomprise a valve body 29 suitably supported in' place of the housing r,there being a valve plug 30 mounted rotatively in the valve body, theplug having a transverse port 31 extending therenected with the port 34and the air tube at is connected with the port 35, sothat by shiftingthe valve plug 30 the blow pipe t may have communication with either oneof the airtubes as or x. The valve plug is provided with an operatinglever 36 to which is connected an operating rod 37 that extends throughthe rear door d so that if the rod 37 be drawn outwardly the valve willbe set as in Fig. 16, and the operator may blow to the wind 'wheel 1",and the rod 37 may be quickly pushed inwardly so as to set the valve asin Fig. 15, thus changing the current from the tube as to the tube x,and therefore direct the current to the vessel y.

In practical use one may blow forcibly through the blowpipe t when thetube-closer z is in mid-position and the blast will be divided partly tothe wind wheel and partly to the vessel y with the result that thepointer j will move but slightly while there will not be suflicientpressure to expel water from the vessel; Then the arm .2 may be shiftedso as to close the tube :v and the operator maybe urged to greatereffort with the result that the pointer j will move farther than before,and when desired the arm z may be shifted so that the tube 2: will beclosed against the abutment 10 with the result that if air now be forcedthrough the blow pipe t air pressure will be created in the vessel so asto force water therefrom out of the nozzle 19. Other operations andresults will be readily understood from the preceding descriptions.
